Product details
Overview
MLX81113KDC-BAB-000-RE from Melexis is a fully integrated automotive-grade LIN slave IC for RGB+W LED ambient lighting control, featuring a LIN 2.x/J2602 transceiver, 16-bit RISC microcontroller (32 kB Flash, 2 kB RAM), four 60 mA current-sink outputs, and four 16-bit PWM channels. It operates across −40 °C to +125 °C and supports autoaddressing via bus shunt method in vehicle cabin lighting systems.
For engineers reviewing the MLX81113KDC-BAB-000-RE datasheet, pinout, applications, or equivalent options, key selection considerations include LIN protocol compliance (J2602), integrated diagnostic capability (LED open/short detection), current-source configurability per channel, sleep-mode current (25 µA typ), and AEC-Q100 qualification for under-hood and interior lighting modules.
Technical Context
The MLX81113KDC-BAB-000-RE integrates a LIN physical layer transceiver and protocol controller compliant with LIN 2.x and SAE J2602, supporting up to 19.2 kBaud frame processing with low interrupt overhead. Its 16-bit pipelined RISC core executes firmware from on-chip 32 kB Flash and leverages a math co-processor for 32-bit MUL/DIV operations.
Four high-voltage I/Os serve as independently configurable current sources (0–60 mA) for RGB+W LED strings, each paired with dedicated 16-bit PWM outputs supporting configurable resolution. Integrated diagnostics monitor LED health (open/short/threshold) and system supply (VBat over/under-voltage), while an internal temperature sensor and battery monitor support ASIL-A safety goals per ISO 26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LIN Compliance | LIN 2.x and SAE J2602 compliant transceiver + protocol controller; enables plug-and-play integration into automotive body networks without external LIN PHY or software stack. |
| LED Drive Outputs | 4× high-voltage current sinks (up to 60 mA each); supports direct RGB+W LED string connection without external drivers or current-setting resistors. |
| PWM Resolution | 4× 16-bit PWM generators with configurable resolution; enables precise color mixing and smooth dimming transitions in ambient lighting applications. |
| Memory Resources | 32 kB Flash (code storage), 2 kB RAM (runtime), 576 B EEPROM (non-volatile configuration); sufficient for LIN stack, lighting algorithms, and user-defined color profiles. |
| Supply & Sleep | Operates from 5.5 V to 28 V; draws only 25 µA typical in sleep mode-meets stringent automotive standby power budgets. |
| Safety & Qualification | AEC-Q100 Grade 1 qualified; designed per ISO 26262 for ASIL-A safety systems; includes watchdog timers, voltage/temperature monitoring, and diagnostic reporting. |
Pinout & Package
MLX81113KDC-BAB-000-RE is housed in an SOIC8 package with exposed thermal pad (package code KDC), optimized for thermal dissipation in compact ambient lighting modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBat | Power supply input | Accepts 5.5–28 V DC; supports 28 V jump-start conditions and integrated battery monitoring (over/under-voltage detection). |
| GND | Ground reference | Common return path for power, LIN interface, and LED current sinks; connects to exposed pad for thermal and electrical integrity. |
| LIN_IN / LIN_OUT | LIN bus differential interface | Internal LIN transceiver pins; support autoaddressing via bus shunt method and comply with LIN 2.x/J2602 physical layer requirements. |
| LC0–LC3 | LED current sink outputs | Four high-voltage, current-regulated outputs (0–60 mA); each drives one LED channel (R/G/B/W) with independent PWM control and open/short diagnostics. |
| VS | Supply sense input | Monitors VBat for over/under-voltage detection and feeds ADC for battery health reporting in LIN diagnostic frames. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LIN Transceiver + Controller | Eliminates need for external LIN PHY and protocol stack implementation-reduces BOM count and firmware development time for lighting nodes. |
| 4× Configurable Current Sources | Each LCx output delivers 0–60 mA with programmable compliance voltage; enables direct drive of common-anode RGB+W LEDs without external MOSFETs or sense resistors. |
| On-Chip Diagnostic Engine | Detects LED open-circuit, short-to-VBat/ground, and threshold violations per channel; reports faults via LIN diagnostic frames for ECU-level error handling. |
| 10-bit ADC with DMA | Measures VS, internal temperature, and I/O voltages with differential/single-ended modes; DMA offloads CPU during sensor polling for real-time lighting control. |
| ASIL-A Safety Architecture | Includes dual watchdog timers, memory ECC (Flash/RAM), voltage/temperature monitors, and safe startup sequence-supports functional safety requirements in cabin lighting systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN-based RGB LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX81115KDC-BAB-000-RE | Same architecture but adds 2× additional current-sink outputs (6 total) and extended ADC channel count; identical LIN compliance and safety features. | Supports RGB+WW+CW or multi-segment lighting zones requiring >4 channels; larger footprint not required unless extra outputs are used. | Select MLX81115KDC-BAB-000-RE when expanding from 4-channel to 6-channel LED control without changing firmware architecture or LIN interface logic. |
| TLE7209-2R (Infineon) | Dedicated LIN RGB driver with 3-channel current sinks (max 50 mA), no embedded MCU or Flash; requires external microcontroller for color sequencing. | Used in cost-sensitive, fixed-color ambient lighting where programmability is handled externally; lacks on-chip diagnostics and EEPROM storage. | Choose TLE7209-2R only if system already includes a LIN-capable host MCU and requires minimal peripheral integration-no standalone lighting node capability. |
Compared with MLX81113KDC-BAB-000-RE, the MLX81115 offers scalable channel count within the same ecosystem, while the TLE7209-2R shifts intelligence to the host-making MLX81113KDC-BAB-000-RE optimal for autonomous, self-contained LIN lighting nodes with diagnostics and firmware flexibility.

It implements both the physical layer transceiver and protocol controller on-die, eliminating external components required for legacy LIN implementations. This ensures full interoperability with standard automotive LIN master nodes.
Does the MLX81113KDC-BAB-000-RE require an external microcontroller?
No-the MLX81113KDC-BAB-000-RE integrates a 16-bit pipelined RISC microcontroller with 32 kB Flash, 2 kB RAM, and bootloader ROM, enabling standalone operation. Firmware for color control, diagnostics, and LIN communication runs directly on the device. External MCUs are unnecessary unless system architecture mandates centralized lighting control across multiple nodes.
How does the MLX81113KDC-BAB-000-RE perform LED diagnostics?
The MLX81113KDC-BAB-000-RE performs per-channel LED diagnostics-including open-circuit, short-to-VBat, short-to-ground, and current-threshold violations-using internal current-sense circuitry and voltage comparators. Detected faults are reported via standardized LIN diagnostic frames, allowing the body control module to log errors or trigger visual alerts without additional hardware.
What is the operating temperature range for the MLX81113KDC-BAB-000-RE?
The MLX81113KDC-BAB-000-RE is qualified for the automotive temperature range of −40 °C to +125 °C (junction temperature), meeting AEC-Q100 Grade 1 requirements. Its integrated temperature sensor and thermal protection logic ensure reliable operation in under-dash, door cavity, and center console environments where ambient heat and radiant exposure vary significantly.
Can the MLX81113KDC-BAB-000-RE drive white LEDs in addition to RGB?
Yes-the MLX81113KDC-BAB-000-RE provides four independently configurable current-sink outputs (LC0–LC3), each capable of driving up to 60 mA. This supports RGB+W configurations (e.g., red, green, blue, and warm-white LEDs) with individual PWM control per channel. The device's 16-bit PWM resolution enables precise white-point tuning and smooth color blending across all four channels.
